Are you tired of compromising your privacy and security when sharing files online? What if there was a way to transfer data that was not only secure and efficient but also put you in complete control? Imagine a file sharing solution that combines cutting-edge encryption with the power of decentralized technology, all while being accessible from any device.

Discord bräuchte mal einen FOSS Konkurrenten mit ActivityPub. Und nein, Matrix ist keine Discord Alternative und funktioniert ganz anders. Zudem Freund*innen die Matrix/Element probierten mochten es nicht und empfanden die Handhabung as umständlich.

I'm probably realizing this later than most, but my level of stress is down significantly since permanently setting my Teams' status to "Do Not Disturb"

Effectively, I am now treating Teams the same way I do Outlook (I turned off toast messages years ago, too)

I just see that :

The #IETF has approved Messaging Layer Security (MLS) for publication. #MLS is an end-to-end #encryption method designed for #groupMessaging. We have been working on integrating a variant of MLS into #Matrix. Keep an eye out for demos in the near future.

D. Balbás et al., "Analysis and Improvements of the Sender Keys Protocol for Group Messaging"¹

Messaging between two parties and in the group setting has enjoyed widespread attention both in practice, and, more recently, from the cryptographic community. One of the main challenges in the area is constructing secure (end-to-end encrypted) and efficient messaging protocols for group conversations. The popular messaging applications WhatsApp and Signal utilise a protocol in which, instead of sharing a single group key, members have individual \textit{sender keys}, which are shared with all other group members. The Sender Keys protocol is claimed to offer forward security guarantees. However, despite its broad adoption in practice, it has never been studied formally in the cryptographic literature.
In this paper we present the first analysis of the Sender Keys protocol along with some prospective improvements. To this end, we introduce a new cryptographic primitive, develop a game-based security model, present a security analysis in the passive and active settings, and propose several improvements to the protocol.
